Zoroastrianism
Zoroastrianism is one of the world’s oldest monotheistic religions, but there are so few adherents left today that few know of this faith.
This religion was founded by Zoroaster in ancient Iran around 3,500 years ago, and was one of the most widely-adopted religions in the world for almost a thousand years. Today, however, there are fewer than 190,000 followers, according to a report by the New York Times.
Zoroastrians believe that there is one God, and his name is Ahura Mazda. This God created the world and all that is in it, and revealed the truth of his nature through the prophet Zoroaster.
The Zoroastrian holy book is called the Avesta, and contains worshipful hymns, myths, stories, and details on how to conduct religious observances.
Most interestingly, Zoroastrians practice sky burials, in which bodies are exposed to the elements atop “Towers of Silence,” so as not to pollute the earth with their remains—they regard death as an evil.
It may not be long before this once-great religion fades completely away, so preserve this bit of human culture by learning all you can.
